UNIT 2 EXPERIENCED AN AUTOMATIC REACTOR TRIP DUE TO GENERATOR PROTECTION ACTUATION
"On May 31, 2002 at 0116EDT, Unit 2 was at 71% reactor power and increasing to 100% when the reactor tripped due to a failure with the generator stator cooling water system. All systems responded as designed. The plant is currently in mode 3, full temperature and pressure."
Both motor-driven and the steam-driven auxiliary feedwater pumps actuated and are currently supplying the Steam Generators with the Main Condenser removing decay heat. The steam-driven auxiliary feedwater pump was subsequently secured and returned to standby. All rods fully inserted with all EDGs available, if necessary.
The licensee informed the NRC Resident Inspector.
